Use keyboard shortcuts to save time editing text – Video Tip
When you open an existing Microsoft Word document, Word places the insertion point at the beginning of the document by default. However, if you would like to move the cursor to the location it was in when you were last working on the document, simply press Shift + F5 on your keyboard.
When you use press Shift + F5, Word performs the Go Back command, which moves the insertion point from its current location to the last location in which a
modification, such as typing, deleting or formatting text, was made.
